¿Cuántos gramos de dicloruro de manganeso se obtienen cuando reaccionan 7,5 g de ácido clorhídrico? MnO2 + 4 HCl = Mn Cl2 + Cl2 + 2 H2O *
Answer:
6.6 g
Explanation:
La ecuación de la reacción es;
MnO2 + 4 HCl -------> MnCl2 + Cl2 + 2H2O
Número de moles de HCl que reaccionan = 7.5g / 36.5 g / mol = 0.21 moles
Dado que;
4 moles de HCl producen 1 mol de MnCl2
0,21 moles de HCl producen 0,21 * 1/4 = 0,0525 moles de MnCl2.
Masa de MnCl2 = 125,844 g / mol * 0,0525 moles = 6.6 g
would the pressure exerted by the gas in the tank would increase if the scuba tank were to increase in temperature?
Answer:
In fact, a full scuba tank will gain about 5-6 psi for every degree of temperature increase. This is one reason that full tanks should not be left in a hot trunk of a car. A tank filled to 3000 psi could easily reach 3500 psi if the temperature of it increased substantially.

How many grams of MgBr2 are needed to create 3.0L of a 4.5M aqueous solution of magnesium bromide?
Answer:
2486 g
Explanation:
First we calculate how many moles of MgBr₂ are required to create such a solution, using the definition of molarity and the given volume and concentration:
Molarity = moles / liters4.5 M = moles / 3.0 Lmoles = 4.5 M * 3.0 L = 13.5 molNow we convert 13.5 moles of MgBr₂ into grams, using its molar mass:
13.5 mol * 184.113 g/mol = 2486 gThe distance between the Grand Canyon and Mt. Rushmore is approximately 1.147 km. What is this in meters?
